So this started one day when I shut the computer down. I went to start and shut it down that way.
When I turned it on again it turned itself off after a few minutes. Then it wouldn’t turn on until a few more minutes, then it again shut itself off…
I thought I heard a clicking sound when it goes off, so I think it’s the power supply.
So I order a new one, wait a week, a slow painful week. And then I install the power supply.
Same issue.
I bring my tech guy over and he plays with the settings in Bios and updates my Bios. It never shuts off in bios so we think it’s fixed…
He has to go because he’s a streamer and he has a tournament. So I rush him home and think problem solved.
I go to be with my computer, get her out of BIOS and after a few minutes she shuts off and doesn’t turn back on. Same problem as before.
So now I’m at a loss. I have no idea what’s causing my problem.
Please. If anyone has any ideas I’d love to hear it. I just want my PC back.


Does the bios have an event log?
Remove all nonessential devices (GPU, all but one stick of ram, etc.) and try again.
You can check the CPU temp by just touching the heatsink. It should be warm to hot, but not so hot that it’s uncomfortable or painful to hold.
Are any other devices in your house having issues? Could be that it’s not getting enough power or wrong voltage.
Does it shut down when you do anything specific like start a bunch of programs or a game? Can you make it shut down if you run a stress test?
Can’t check PC isn’t coming on at all now
